IMPROVEMENT. 1Nl HYDRAN'TS.

vfI'O'ALL WHOM 'IT MAY CON CERN Be it'known that I, THOMAS BROWN, ofAllegheny City, Allegheny county, and State of Pennsylvania, haveinvented Ya new and useful Improvement in Hydrants; andrl hereby declarethat`the following -is a full, clear, and exactdescription of theconstruction and operation of thesame, `reference being had totheannexed drawings, andto the letters of reference marked thereon.

The nature of myinvention consists in providing the stem ofstop-valvesin hydrants with a screw or worm, andalso furnishing thereservoir with a nut of the 'same pitchasthe screwed stem, throughwhich-nut the stem works and rotates, a movable cap, through whichthevspout of the .hydrantp'asses, an inclined slot or groove in the-maincolumn of the hydrant, through whichthe spout `passes and travels, beingused in combination4 with the ordinary valve, reservoir, inletfpipe,supply-pipe, and spout, forthe purpose of regulatng'the supply of water,the whole being constructed, arranged, audoperatingin 'themannerhereinafter described. Y'

' To enable others skilledin the'art of constructinghydrants'to makeand'usemy. invention, I will proceed vtoidescribe its construction andoperation. l A I In the accompanyingfdrawings- Figure 1 `represents aside elevation of my improvements in hydrants;

Figure 2 represents a front elevation of my improvement in hydrants.

Figure 3 represents a section of my improvementinhydrants.

Figure 4 represents' an-elevation ofrmy-improved valve, yshowing thescrew o r Worm.

Figure 5 represents a section of the reservoir and inlet-pipe, showingthe valve, screw, nut, andrvalve-seat.

s Figure-6 represents the inclinedslot or groove, near the t'op of maincolumn.

Figure'represents a plan of reservoir,` showing valve-seat.

In the accompanying' drawings'- v l .A represents the main column of anordinary hydrant.

B represents the inclined slot or groove, in which the spout moves.

C represents the movable cap, in which I maken perforation 'qual to thediameter of the spout, whichl .passes through it. 4

- D represents the' bent spout. Y Y l -Efrepresents the supply-pipe,connectedwith the `bent spout Afl), by means of a female elbow, F, whichsupply-pipe E is furthermore connected with the stem G otthe valve, bybeing screwed to it.

G represents the; hollow stem ofthe valveH. A

H represents the valve, with openings at the side, as at K.

J represents thesworm or screw-on the hollow valve-.stem Gr of the valveH.

-L represents the nut, in which the worm or screw J' passes andrevolves, \vl1i ch 'nfut L is connected with the reservoir, by means o``beingscrewed to ityas at N.

M represents the reservoir. f O represents the inlet-,pipeywhieh is partof the reservoir'M. P represents the raised Vvalve-seat, which is alsopartofthe reservoirM'. 'Q represents the base, which is connected withthe Vrnain'column Albymeans of screws, and Valso attached -lo 'thereservoir M by means of 'the screwRand the nuts; l

T represents a ring, of gum or leather, pressed int'oa dove-tailed`recess .at the bottom 'of'valve H, which gum or leather bears light uponthe raisedJalve-seat -P, Vwhen the valve H is closed.

Ipropose, for the-purpose of manufacture, making the main column A ofwood, castion', or any other suitable materiali; the movable capl O fofthe same' material the spoutD of veast or'wrought iron, or malleablemetal;` the female elbow Feof cast or wrought iron, -or malleable metal;the supply-pipe E of-wrought 'or cast `iron; the base,'Q,'of wood orcast iron, and the remaining larticles of brass, except the joint-ringT, which 'would be of gum or leather.

. The form and mode of making the various parts-ofmy"improyemeutn'hydrants.,jIleave to the taste,.skill,. and judgment ofthe mechanic.v

`and operating asa-.nd for the purpose set forth'.

vThe operation of working my improvement in hydrants is as follows, viz:By movingrthe bent spout D around a quarter of a'evolution, which'spbutvD moves the cap C, by passing through o. hole in it, of the samediameter as the spout D, and the spout D moves lalong the inclined slotB of the main column A. The bent spout Dby the same operation, and 'at'the same time moves around, in the same direction thc-supply-pipe E, asit is connected tothe spout D by means of the femaleelbow F, and at thesame time rotates the screwed hollow stem Gr of the valve H. As thesupply-pipe E is connected with the stem G, by means of being screwedinto it, as at I, andthe worm or screw J on the hollow stem Gr of thevalve-VH, working in the nut L, raises the valve-H and the joint-riugl'lfrom the face of the valve-seat P, the water from' the inlet-pipe Opasses up through the valve-seat iP into reservoirM, and throughopenings K inv the valve H, through the hollow stem Gr, up through thesupply-pipe E, and .delivers'itself from. the spout D. When suihcientwater is furnished, by turning the spout back 'again to its originalposition, 'it operates revcrsely, and brings the valve H and joint-ring'.l down upon the raised valve-seat P, and cuts off the supply.

When the supply of water is cutoif, the spout D is over andin a directline with inlet-pipe O.

When the supply of water is being delivered, the spout D is at rightangles with the inlet-pipe O.

The inclination of the slot Bis such as to allow the spout D to risevertically the same distance as the valve H is lifted from its seat,when the spout'is turned. A f

I do not claim operating a hydrant by the/turning of the spout, suchdevices being'herctofore in use; but, having thus describedthe nature,construction, and operation of my iuvention WhatI lclaim, and desireto'secureby Letters Patent, is

1. The spout D'y and pipe E, with thein'clined slot B, and movable capC,fcombincd, arranged, and operat ing substantially as described. .l

'- 2The hollow valve H and hollow screwed stem G, with the nut L,pipe E,und` spoutD, combined, arranged,
